ps. I used sd0c. I suspect this has something to do with an incorrectly
partitioned disk! (Surprise, surprise

I haven't got any further yet ... but hope to resolve this tonight.
( I'll keep on bashing away :)

So BASICALLY it's seems that I don't have my drive setup right.
It's not an issue of SCSI bootability (at this point:).
I figure I need to work out how to partition the drive, but I'm still not
sure
if I can update the bootblocks at any time (ie. afterwards).

Also, from what I can see at
http://www.netbsd.cx/src/netbsd-current/vax.GENERIC.html
I figure that DSSI support is not a default option.
What do I need to do?

Thanks,

Marcus.
